Milo500 Posted June 21, 2016 Share Posted June 21, 2016 Pretty much says it in the title haha. I have converted to single turbo (from twin turbo) and am installing the ecu and injectors very soon... However I am in need of information on what the twin turbo auto gearbor will take horsepower wise (at the crank) In stock form. I am shooting over 500bhp, hopefully between that and 550bhp...has anyone got an auto running that power on single? How reliable has it been? How many boxes have you been through? What is a reliable bhp figure to run it at? What would be it's max power to run it at, even though it would be unreliable?

SaqTRD Posted June 21, 2016 Share Posted June 21, 2016 Hybrid box with Hi Stall and massive oil cooler would be my shout for a single setup. Torque and Heat kill boxes. Quote Link to comment Share on other sites More sharing options...
Chris Bailey Posted June 21, 2016 Share Posted June 21, 2016 Heat and torque kills autoboxes, I'd recommend 2x trans coolers and not run over 550lbft. But there's no guarantee how long it will last. If you can stretch your budget for a hybrid box or built box that would be ideal. Quote Link to comment Share on other sites More sharing options...
X13mgr Posted June 21, 2016 Share Posted June 21, 2016 And buy my box as a spare. Just in case Quote Link to comment Share on other sites More sharing options...
Milo500 Posted June 21, 2016 Author Share Posted June 21, 2016 I'm probaby going to sound very dense haha...I have done all work on cars, apart from boxes...what is a hybrid box, and a "hi-stall" ... I allready have an aftermarket oil cooler (as the rad is aftermarket) but not sure if it is large enough, so will probs look at getting another as well.
